Intermediate algebra

Written for students who are moving beyond basic algebra, this textbook by Alden T. Willis from Wadsworth Publishing presents its material so that it is easy to follow and connects to students' own experience. Its explanations are plain and to the point, supported by worked examples meant to stretch learners while still rewarding their effort. Each topic is developed in detail, and the book keeps returning to the broader principles that govern algebra, so students see both the individual procedures and the reasoning behind them.
